copy

Copies a vector to another vector.

Description

The copy routines copy one vector to another:

y \leftarrow x

where x and y are vectors of n elements.

API

Syntax

namespace oneapi::mkl::vm {
  void copy(
  queue &exec_queue,
  std::int64_t n,
  buffer<T,1> &x,
  std::int64_t incx,
  buffer<T,1> &y,
  std::int64_t incy)
}

copy supports the following precisions and devices.

T

Devices Supported

Input Parameters

exec_queue

The queue where the routine should be executed.

n

Number of elements in vector x.

x

Buffer holding input vector x. The buffer must be of size at least (1 + (n 1)\*abs(incx)). See Matrix Storage for more details.

incx

Stride of vector x.

incy

Stride of vector y.

Output Parameters

y

Buffer holding the updated vector y.
